5. UNCLASSIFIED “It’s All About the Soldier” Definition of Net Zero – Energy Initiative A Net Zero Energy Installation (NZEI) is an installation that produces as much energy on site as it uses, over the course of a year. To achieve this goal installations must first implement aggressive conservation and efficiency efforts while benchmarking energy consumption to identify further opportunities. The next step is to utilize waste energy or to "re-purpose" energy. The balance of energy needs then are reduced and can be met by renewable energy projects. Energy Security is the foundation of the NZEI! USAG – Ft Hunter Liggett Solar Hot Water Solar Vent Preheat Ground Source Heat Pump Daylighting todd.a.dirmeyer@us.army.mil5
